GAS-BURNER.

Specification of Letters Patent.

Patented Aug. 20,' 1907.

. Application filed January 4, 1907. Serial No. 350,703.

Our invention T lllita to gas burners and has for its Object. theprovision of a device of this character constructcd in such nmnucr thatthe proportions of air and 1 gns uni he readily regulated, andconstructed in such manner that it plentiful supp y of all! may heobtained Further objects and :tdtnntztges ol' the invention will be setforth in the detailed description which now l'ol "lows:

in the net-tnnpttuyiug drawing: Figure l is a vertical section of it gasburner constructed in ztccordalnce with i the invention,illustrating-the gns vnlve and pipe upon which it is supported, inelevation, and, Fig. 2 is it horizontal section upon line as x of Fig.l. t

Like numerals designate corresponding parts in both of the figures ofthe d rowing.

Referring to the drawing, the numeral 5 designates a gas supply pipe andthe nuniernl 6 designated-a valve controlling the ilow of gas from thepipe 5 to the nipple 7. Brackets b serve to support it c-ip 9, thebottom 01* this cup forming a spider 10. The cup\9 supports :tcylindrical casing 11 which is closed at the top and is perforatedaround its sides adjacent the top as at 12. A platealB spans this casingand is provided with a depending l'unnel 14, this funnel opening throughthe plate l3as at 15. A tube 16 is centrally located within the casing11, extends through the funnel .14 and is threaded at 17 into thespider, said spider being enlarged its at. 18 for this purpose. A locknut 19 serves to retain the tube 16 in its adjusted position, it beingunderstood that this tube may be screwed up or down for a limiteddistance. Threaded upon the lower end of the tulle it} is it sleeve 20whith lies over the nipple 7.

The opcrittitni 01' the device is 11-5 follows: Gas is admitted throughthe valve (3, passes through the nipple 7 and sleeve 20 to the pipe 16.During its passage from the'nipple 7 to the sleeve 20, a certainquantity of air is mixed with the 'us and the proportions between theair and gas may be readily determined by screwing the nipple 20 up ordown upon the tube 16. The air and iug H, where it is igniteth the gttsburning iu'ound the edge of this casing and iorutiu; n pointed lltuncabove silitl casing. .\ll nlso passes between tltt arms of the spiderand up tluough the tunnel l-l mixing with the nit'ttudcns from the tuhel5 :it the upper end oisnid tube and providing 1t perfect coiuhustion.Screws 21 provide menus for securing the casing it to the (,up 9.

It has been found that n burner constructed {IS herein shown anddescribed, produces :1 clear blue iluiu indientive of perfect combustion:llltl yields a maximum degree of hunt.

\\hile the elements shown and described are well adapted to serve thepurposes for which they tilt int nded, it is to he understood that theinvention is not limited to thtprecise construction set forth, butincludes within its purview such changes as may he made within the scopeof the appended claims.

What we claim, is:

i. in a device of the character described, the combination with :1(using which is closed nt the top and open tit the holtoiu and which has:1 series of openings foilped through llll wall thereof ndjucent saidclosed top, of 11 Hill! centrally located within suid casing andterminating between the top of the cnsing and the center of the (Basins,an inverted funnel surrounding said tube, :1 plate which supports suidfunnel and which closes the cnsing around said funnel, n mixing sleevelocated upon the lower end of the tilllt, and'u gas nozzle adapted to.discharge into said nilxi ig sleeve.
